I have seen here a minor problem in the upgrade process. Seams to more a bug in the debian upgrade process.I had already installed the package lighttpd. During the upgrade process I got an error about a missing file:
/etc/lighttpd/conf-enabled/10-auth.conf
This is a link to /etc/lighttpd/conf-available/10-auth.conf which was missing.
The reason is the new package has renamed the file to
/etc/lighttpd/conf-available/5-auth.conf
I corrected the link and repeated the upgrade process. It finished now successfully.
/etc/lighttpd/conf-enabled/10-auth.conf
